Understanding Linear and Exponential Functions

The video tutorial explains how to determine if a table of function values represents a linear or exponential function. Linear functions are identified by repeated addition, while exponential functions are identified by repeated multiplication. The tutorial analyzes two tables: the first shows a linear function with a consistent addition pattern, and the second shows an exponential function with a consistent multiplication pattern. The video also demonstrates how to graph these functions on a coordinate plane, highlighting the differences between linear and exponential graphs.
